G'day all... I am currently having trouble with the irq_tables.c produced by getpir.
I am receiving the following error from the linuxbios boot: Checking IRQ routing tables.../root/aug2002/lb/freebios/src/arch/i386/lib/pirq_routing.c: 24:check_pirq_routing_table() - irq_routing_table located at: 0x0000b0c0 /root/aug2002/lb/freebios/src/arch/i386/lib/pirq_routing.c: 31:check_pirq_routing_table() - checksum is: 0x26 but should be: 0x7a /root/aug2002/lb/freebios/src/arch/i386/lib/pirq_routing.c: 49:check_pirq_routing_table() - checksum error in irq routing table done. Copying IRQ routing tables to 0xf0000...done. As can be seen from irq_tables.c, the checksum internally is 0x26, and getpir did not report any errors when it downloaded the table. Does anyone have any ideas? John... irq_tables.c follows: /* This file was generated by getpir.c, do not modify!
